The formation of the China-led AIIB offers the opportunity for emerging economies to have a greater say in the global financial landscape. This paves the way for the development of greater connectivity in the Asian regional economy and more inclusion of developing economies in Asia.

The One Belt One Road initiative, including the AIIB, will boost low income economies in Asia and create low cost production centers in these countries. These "Asian frontier economies" may take some of the market share from China as a result.

Switzerland's new membership with the AIIB is expected to boost the development bank's capacity and legitimacy. Many more countries have prepared applications and are hoping to become AIIB members. However, although Taiwan had previously applied, their new government has refused to play by China's rules for membership in the bank. The Chinese Government has requested Taiwan follow the "Hong Kong" model in order to become an AIIB member, which would undermine the sovereignty of Taiwan.

The AIIB has been called a "constructive addition" by a top official at the U.S. Treasury. However, according to the Treasury undersecretary for international affairs, U.S. investment in the AIIB is still not on the table.
